UNITED STATES PATENT OFFICE.

WILLEY J. FELLHEIMER, OF NEIV YORK, N. Y.

VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 436,701, dated September 16, 1890.

, Application filed January 30,1890. Serial No. 338,554. (No model.)

To all whom it may concern:

Be it known that I, WILLEY J. FELLHEIMER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to an improvement in ventilators of the kind adapted to ventilate the interior of cars, cabins, and similar spaces and the invention consists in the details of construction set forth in the following specification and claims, and illustrated in the ac companying drawings, in which- Figure l is a plan view of the ventilator. Fig. 2 is a sectional side elevation of the ventilator. Fig. 3 is a section along 00 00, Fig. 2. Fig. 4 is a section along y y, Fig. 2.

In the drawings, the letter B indicates a roof of a car to which is screwed or fixed a bushing h. To the bushing 72 is screwed a thimble f. Said thimble has a conical journal hearing or seat in its upper end, in which is arranged the conical journal m, fixed to the fan-shaft u, to which shaft are fixed the fanblades or screw-blades d.

The driving-blades c are secured to the fanshaft to, a slotted collar 0 preventing theblades from turning independently of the shaft. The blades 0 enter the slots in the collar 0, and said collar has a tongue D, through which a screw E is passed into the shaft a, fixing the collar to the shaft. The lower parts of the blades 0 are secured to one another by the tongues F and screws or rivet-s G.

The blades 0 rotate-in a cap orhood A, said hood being semi-cylindrical or open on one side, so as always to leave one blade cexposed to the wind, so as-to secure rotation of the blades 0 and shaft to. V The hood A is supported by arms 19, extending from a collar H, rotating about the thimble f. A vane 17 keeps the front of hood A turned to the wind. Said vane is held in place by a plate or plates e and by an arm K, secured to the vane by a screw K. i

The arm K has an eye or head L, passing over the shaft a, and a lug or screw M, pass ing through the head L, enters a groove in the shaft a, so as to prevent the arm K and hood Aslippingoif theshaft, but leaving the shaft free to rotateindependentlyof the hood. The rotation of the shaft it. rotates the screwblades d, so as to draw air through the opening S into the housing n, surrounding the blades (1, said air being forced out of the housing 0?, through the openings g'into a channel I in the car-roof B. Said channel I leads to the open air in any suitable way-as, for example, by means of openings (not shown) at the side of the car or cabin, which openings can be covered or protected by netting or gauze to prevent entry of dust, while allowing outflow of the air.

The screw w actuates a leverN, swinging about a fulcrum 0, so as to press an elastic or rubber head or block w more or less firmly against shaft it, thus securing a brake for the shaft to regulate the speed of rotation.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. The combination of a stationary thimble having a journal-bearing at its upper end portion and a bushing fixed to its lower end portion, a rotary shaft extending through the bushing and thimble and having a journal arranged on the said journal-bearing, afan mounted on the shaft below the bushing, a

housing inclosing the fan and having an airdraft orifice, a series of driving-blades fixed to the shaft above the thimble, a collar journaled to rotate upon the upper end of the thimble, a rotary hood open at one side, loosely mounted on the fan-shaft, and having arms rigidly connected with said rotating collar,

and a vane rigidly connected with the hood,

whereby the driving blades projecting through the open side of the hood are presented to the wind, substantially as described.

2. The combination of a stationary thimble having a conical journal'bearing in its upper end and a fixed bushing secured to its lower end, a rotary shaft extending through the bushing and thimble and having a conical journal setting in the journal-bearing, a fan mounted on the shaft below the bushing and thimble, a series of driving-blades fixed on the shaft above the thimble, a housing inclosing the fan and having an air-draft opening,

'a collar journaled to rotate upon the upper end of the thimble, a rotaryhood open at one side, loosely mounted on the fanshaft, and

4 rigidly connected with the rotating collar, and

a Vane connected wit-h the hood, whereby the driving-blades projecting through the open side of the hood are presented to the wind, substantially as described.

3. The combination of aroof havinga horizontal air-escape channel andair-inlet orifices opening thereinto, a stationary thimble extending through the roof and having atits upper end a journal-bearing and at its lower end a fixed bushing, a shaft extending through the bushing and thimble and provided with a journal setting in the journal-bearing, a fan mounted on the shaft below thebushing and thimble, a housing secured to the roof inclosing the fan and having an air-draft orifice, a series of driving-blades secured tothe shaft above the thimble, a collar journaled to rotate upon the upper end of the thimble, a rotary hood having an open side loosely journaled on the shaft and rigidly connected with the rotating collar, and a vane secured to the hood, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

WILLEY J. FELLHEIMER.
